OKLAHOMA CITY (KFOR) - Video given to NewsChannel 4 from the assistant district attorney's office gives a first look at how Geneva Robinson used her alter ego, "Nelda the Witch," to torment her granddaughter.

Robinson was arrested back in 2014 for child abuse and has been sentenced to three consecutive life sentences in prison.

It's a nightmare inside a house of hell.

Video shows Robinson dressed up as "Nelda the Witch."

"Oh no! She might take the doggies," a child can be heard screaming.

"I won't hit grandma! I won't be mean!" a child can be heard crying.

The trauma just keeps going, and it appears multiple children are in the room.

At one point, Robinson can be heard saying "give me a fork and a knife."

At another point, a man appears in the video.

"Grandma's sick because of you! Go with the witch," he said.

A child can be seen clinging to the mans shirt, which comes off, and it appears to be a man we interviewed back in 2014 named Joshua Granger.

"She never dressed up as a witch to punish any of those kids," he told us.
